Insurance: an underwriting machine, now retooling itself

Insurance is structurally an information business, which makes it the cleanest target for AI in financial services. McKinsey pegs the gen-AI revenue opportunity at $50-70bn, Conning finds 90% of insurers already somewhere on the gen-AI journey, and Chubb's CEO has committed to automating 85% of underwriting — even as a UnitedHealth class action over an algorithm with an alleged 90% error rate shows where this goes wrong.

01 · The thesis

The cleanest AI target in financial services — and the most legally exposed

Insurance runs on the cost of acquiring, pricing and adjudicating information, which is exactly the cost AI compresses. McKinsey estimates gen AI could unlock $50-70bn in revenue and lift underwriter productivity by up to 50% while cutting underwriting cost by up to 30%; in selected cases it has pulled quoting times from weeks to hours and decision times to roughly 12 minutes. Conning's 2025 survey finds 90% of insurers somewhere on the journey and 55% in early or full deployment, and software-and-data spend has grown about 20% a year over the five years to mid-2025.

But adjudication is also where AI becomes a liability rather than an asset. UnitedHealth is in a class action over the nH Predict tool — an algorithm plaintiffs say carried a 90% error rate, with nine in ten appealed denials reversed — and a March 2026 order compels broad discovery. Regulators are converging fast: 24+ states have adopted the NAIC model bulletin, and Colorado's quantitative bias-testing regime expanded to auto and health in October 2025. The winners will be those who treat governance and explainability as the product, not the overhead.

We plot the listed players on two editorial axes — how exposed each is to AI disruption, against how ready its data, brand and position are to be the answer. The figures in the table are sourced; the placement is our read.

03 · The two clocks

The spend, and the payoff

Spend is real and growing ~20% a year; the payoff is concentrated in underwriting and claims, and gated by governance.

Source: Fortune Business Insights, AI in Insurance Market (2025); gen-AI sub-segment per market-research estimates

The AI-in-insurance market was about $10.4bn in 2025 and is forecast toward $13-15bn in 2026, with software-and-data spend growing roughly 20% a year over the five years to mid-2025 (Fortune Business Insights, McKinsey).

Payoff clusters where the data is structured: claims, underwriting, pricing and quoting already account for 58% of disclosed AI use cases, and vendors report straight-through processing rising from 10-15% to 70-90% (Vantage Point).

The gen-AI slice specifically was about $1.1bn in 2025 and is projected toward $14bn by 2035 — fast growth off a small base, with most carriers still in pilots rather than full deployment (Yahoo Finance / market research).

06 · The exposure read

Who’s defensible, who’s at risk

AI rewards clean, structured advantage and punishes friction. The line runs through who owns the data, the brand and the customer — and who is merely a step the technology can route around.

Defensible

  • Data and core-platform incumbents (Verisk, Guidewire, Duck Creek) sell the picks and shovels every carrier needs, capturing margin regardless of which insurer wins.
  • Telematics-and-data-rich carriers (Progressive, Root) turn proprietary driving data into tighter loss ratios that pure-LLM entrants cannot replicate.
  • AI-native insurers with governance discipline (Lemonade) convert a lower cost base into premium growth — Q4 2025 in-force premium up 31% to $1.24B.
  • Explainability-first vendors (Akur8, Cytora) win as bias testing and audit requirements make transparent models a purchasing prerequisite.

At risk

  • Carriers that automate adjudication without auditability (UnitedHealth) face the nH Predict pattern — a 90% alleged error rate and forced discovery turning AI into legal liability.
  • Low-differentiation distributors lose ground as conversational AI and embedded quoting collapse the acquisition-cost advantage they once charged for.
  • Late-moving incumbents (GEICO/Berkshire catching up) pay more later to close pricing-sophistication gaps competitors built with a head start.
  • Sub-scale insurtechs without a data moat struggle as the value accrues to whoever owns proprietary risk data, not to thin-margin front ends.
Most of the headline productivity figures come from vendors and consultancies with a stake in adoption; real-world deployments are still mostly pilots, and the UnitedHealth case is a reminder that the same automation that compresses cost can manufacture systemic, discoverable harm.
